Hello, at first I found these images on Pinterest and I manage to find a Tumblr that seems to be their original source ( http://skamicon.tumblr.com/post/155765696231/skam-quotes-lockscreen-previews-x-x-x-x ) .

I don't know if it's really the original source tho. At least I think it's the most relevant source I found after I tried googling it by image.

Some of the fonts here have shadow, I guess it's just an effect? Can anyone help me?

 

 

 

 

Arial. The shadow is an applied effect (or just the same text in a different color placed underneath).
